Project description:To study the effect of pregnancy on mouse mammary epithelial subpopulations, epthelial cells derived from virgin or pregnant (12.5 day pregnant) mice were isolated using fluorescence-activated cell sorting. After elimination of haematopoietic and endothelial cells, two distinct epithelial subpopulations were sorted using antibodies against CD29 and CD24. Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as mammary stem cell enriched (CD29hiCD24+) and luminal (CD29loCD24+) respectively (ref: Shackleton et al, Nature 2006). Microarray profiling was used to compare gene expression profiles of the two subpopulations in 12.5 day pregnant and virgin mice.
Project description:To identify genes expressed predominantly in the ventral skin dermis of pregnant mice, we performed DNA microarray analysis by using isolated dermal tissues from ventral skin at 0 and 15 dpc, PP2-injected ventral skin at 15 dpc, and dorsal skin at 15 dpc.

Microarray profiling was used to compare gene expression profiles of the two subpopulations in 12.5 day pregnant and virgin mice. For each biological replicate, mammary gland from virgin or 12.5 day pregnant FVB/NJ mice were collected and digested to obtain a single cell suspension. CD45-CD31-TER119- cells were then sorted based on the expression of cell surface markers CD24 and CD29. There were 4 pools of pregant mice and 3 pools of virgin mice.
Project description:We found Shh overexpression in epidermis can induce hair follicle neogenesis in wounded skin. We analyzed gene expression profile in dermis and epidermis of WT (control), LSL-Shh (Shh overexpression in epidermis) and E14.5d skin
Project description:In the epidermis, CCR4, CCR6, CCL20 and CCL27 were higher in ATLL than in MF. We obtained the epidermal samples from MF (n=5) and ATLL (n=5) with the aid of laser microdissection. Complementary RNA amplification were used for gene expression profiling by microarray analysis. We compaired MF with ATLL in epidermis. We obtained the epidermal dermal samples from MF (n=3) and ATLL (n=3) with the aid of laser microdissection. Complementary RNA amplification were used for gene expression profiling by microarray analysis. We compaired MF with ATLL in dermis.
Project description:To uncover the genes related to nervous system increased in the process of intrinsic aging, microarray analysis was performed with the dermis and the epidermis of buttock skin obtained from the young and old volunteers. We found that 23 genes related to the nervous system were upregulated more than two-fold in the dermis of the aged. Conclusively, our results suggest that hyperinnervation together with elevated factors related to SP (substance P) signaling may result in the erroneous sensitization (e.g., pruritus) in the aged skin.
Project description:The gene expression profile of the adult zebrafish cornea was assessed in comparison to those from closely associated surface tissues: the dermis and epidermis. This SuperSeries is composed of the SubSeries listed below.
